Paragraph 0019, (2017/08/29)
The invention relates to a 5,5'-diaryl-3,3'-diamino-4,4'-dimethoxybenzophenone compound and a preparation method thereof. The preparation method comprises the following steps: carrying out nitrification on 4,4'-dimethoxybenzophenone firstly to obtain 3,3'-binitro-4,4'-dimethoxybenzophenone, then carrying out reaction on the 3,3'-binitro-4,4'-dimethoxybenzophenone and N-bromosuccinimide (NBS) under the acid condition to produce 5,5'-dibromo-3,3'-binitro-4,4'-dimethoxybenzophenone, then adding a reducing agent to covert the 5,5'-dibromo-3,3'-binitro-4,4'-dimethoxybenzophenone to 5,5'-dibromo-3,3'-diamino-4, 4'-dimethoxybenzophenone, and finally carrying out reaction on the 5,5'-dibromo-3,3'-diamino-4,4'-dimethoxybenzophenone and arylboronic acid containing various large conjugated groups to obtain the 5,5'-diaryl-3,3'-diamino-4,4'-dimethoxybenzophenone compound containing large conjugated groups. The 5,5'-diaryl-3,3'-diamino-4,4'-dimethoxybenzophenone compound and the preparation method thereof are simple in synthesis route, convenient to operate, high in yield and cheap and available in raw materials, and thus the production cost is greatly lowered.
